Abstract
Fluid impermeable, protective clothing is usually impermeable in both directions, and thus sweat is unable to evaporate from the skin or from inner clothing. A buildup of moisture is uncomfortable and, if prolonged, can cause pain and injury. A simple solution to the problem is to insert a two-layer liner in the impermeable clothing which will absorb the sweat. The liner includes an inner layer of vapor permeable, liquid impermeable material such as microporous Teflon (trademark) film, microporous polyurethane film or a hydrophilic polymer coating, and an outer layer of a material highly absorptive of both water vapor and liquid.
